tems, of'which the following isga specifica-v tion.

' This invention relates to a heating systeml deslgned es ecially for 4use in connection with open re places in which grates are placed-,and has for its object the more uniform distribution of heat throuffh the room 1n which the said grate is placediby increasing the circulation of air throughout the room, and also the conveying of heatto other rooms adjacent to the one in which the grate is located. Y

'The invention consists in. the novel fea- ,tures'of construction,hereinafter fully de scribed, and pointed out` in the claim, and

shown 1n the accompanying drawings.

In the drawino's A represents a chimneyp thelower end ot which communicates with an open fire-place A', in which is arranged l a grate A2, back of which isplaced a fireback A, preferabl curving forwardly and A4 has its forward edge secured to' or bearing upon the` upper. ed

0e ofthe re-back A, and extends rearwardly' Ato v the rear-wall of the chimney A. By means of this construction a heating chamber B, is formed at the rearof thegrate and within the lire-place and in alinemeut with the chimney flue.

Below the flooring upon which the grate A` rests, is'formed an .air chamber C, and

an air passage C', conveys the outer air into this chamber from which 1t passes into the heating chamber B, through suitable perforations C?, formed in the floor of the chamber B, which Hoor is a continuation of the flooring upon which the grate A2, rests. `A' hot airpipe D, leads upwardly within the 45. into ybranches D', which at theirupper ends -dischargel through registers D2, into upper rooms. yThe pipesl D', are 'also provided r with branches E,.which discharge laterally chimney flue from the hood A4, and divides into Y lower rooms one.- of. which lis vthe room in which the grate A2, is located. From the other `lower room leadsfan` Sfshaped pipe,

at F, and the upper endI of which opens downwardly into the heating' chamber B, and .within the .hood A4. A pipe G leads from the heating chamber B and discharges heated airinto'the room in which the grate is located at la point immediately above the fireplace.

In uset-he outer air will be drawn through I the passage C', into the air chamber C, from whence'it will pass into the heating chamber B, and 'will be carried upwardly through the lhot air pipe D, and discharged through the branches D and E. The warm air discharged through one branch E will circulate through said room as the cooler air will be forced into the pipe Fand will be discharged downwardly into the heating chamber B where it will be heated and discharged `through the pipe D and its branches. It will 'also benoted that the vertical portion of the pipe LF is'in the chamber B so that the air euterlngsaid pipe at its lower end will be- 1come heated 'as it passes to the upper end of -said pipe. This heated current can escape only by moving downwardly into the upper hottest portion of the heating chamber. Owing to the reluctance of this downward movement, and its retarding effect on the ascentA of the air entering the chamber 'l'ionrthe passage C all of the air in said heating chamber will be more or less superheated, thus causing the discharge of hot, and not merely warm, air through pipe D and its branches.

Having thus fully described my invention, what l claim as new and desire to secure by Letters Patent is z- A heating system of the kind described comprising in combination with a chimney flue andan open fireplace, a grate, a fireback curving forwardly and upwardly, a hood'A4 having its forward edge bearing upon the upper edge of the fire-back and ext-ending rearwardly to the rear wall of the chimney, thereby forming a heating chamber in the rearA of the grate and within the fireplace, said heating chamber being in alinement with the'chimney flue, means for e 'admitting fresh air into the bottom portion of the said heating chamber, a hot air pipe leading upwardly through the chimney lue ,and communicating at-its lower end with the pipe dischargn?` air downwardly into the xnuncating respectively with rooms upon the heating chamber.
